Overview
Description
32-bit microcontroller capable of up to 240 MHz operation. Employs the RXv2 core, a more powerful evolved form of the RX core that was used in previous RX devices, while maintaining compatibility. Realizes 1160 CoreMark, the top performance among microcontrollers with built-in flash. Cache optimized for flash memory (AFU) can realize equivalent of 240-MHz zero wait flash memory access. The wait time for the CPU is a mere 1 cycle thanks to the 120-MHz zero wait access flash memory. This extremely high-speed memory access brings out the full performance of the CPU. Built-in AES, DES, SHA, and RNG protect data on a network. Built-in trusted memory function forbids reading of code from a specified area of the built-in flash memory. Equipped with up to 4 MB of code ROM and 552 KB of work RAM to support the increasing code/work area demanded by IoT network control and other applications.
